1960s handmade collared babydoll dress

this is a super cute unique piece with no tag that i think someone made in the 60s!!!! in my professional opinion. the fabric is a very specific and weird synthetic material, it’s quite stiff and not stretchy at all. it’s so cute tho and so sweet it has a collar and a little tie type round piece in the middle, it zips in the back and it has a DRAWSTRING!!! the length from shoulder to bottom is 34 inches and the waist goes up to 36 inches but the drawstring allows that to be smaller!!!
